This has been a most productive
thread! I've shut off the Windows Time service and downloaded/installed the
Meinberg NTP client as well as the GUI. My system time is now dead-nuts in sync
with WWV/WWVB. Thanks to all who helped! Slowly but surely, this new
HP Win7 64-bit machine is coming to life.

I've not read anything about the W7 time client specifically, but the
general trend is that it has come closer to actually adhering to the relevant
RFCs with each release (i.e. 2k was bad, XP was better). Vista is said
to be an actual NTP implementation and not just SNTP (Simple Network Time
Protocol) so maybe W7 is, too.

What I do is disable Windows'
time service and replace it with the Windows port of the NTP client. See
http://www.meinberg .de/english/ sw/ntp.htm
Meinberg specifically lists W7 as being supported which isn't really a
surprise. No charge for the software since it's just a Windows port of
an open source project.

NTP, BTW, was developed by W3HCF over the last
30 or so years.

If you are hell-bent on making Windows' time service
work, see these two references:

As
I said, I've not seen anything specifically about W7's time client. If
it is a well-behaved and standards-compliant NTP client then that's good, but
I'll bet it still needs tweaking to get good time out of it.

If you run
any form of UNIX including Linux, of course NTP is built-in and you don't have
to worry about any of this.

Further on the initial subject of
this thread -- i.e., using D4 on Windows 7 --

According to Doug VE5UF, you CAN
make D4 work on Windows 7, but you have to do the following:

(a)Shut off the Windows Time service

(b) Run D4 in
Administrator mode

(c) Apply
Compatibility Mode for Windows XP SP3 to it

The last two items are checkbox
options selected on the Properties dialog box for the D4 executable. Right-click
on D4.exe in Windows Explorer and select Properties from the menu to get
there.

However, I haven't bothered to
actually do this because the public-domain Meinberg NTP client referred to below
in this thread uses a drift correction capability, which D4 does not. This makes
it more accurate than D4 is anyway, and it's also free.
